Check the file size of your gta_sa.exe file. It should be 13.7MB, if it's not then you may have a corrupt or incomplete file. Me and my friend Cap1 were working on this for days on his new pc he bought and it just kept loading the single player and a white screen then nothing. Well he noticed his old pc had the full 13.7MB gta_sa.exe file (that worked), and his new pc had one that was 8MB (didnt work). So he copied the full gta_sa.exe file from his old pc and sure enough it loaded up multiplayer immediately!! Try it!!
